PLA Special Notice FY25 Joint Base Lewis McChord Multi Domain Task Force Buildings 3221-3222

USACE Seattle District has a requirement to convert two (2) existing barracks buildings into operational facilities for 3 tier levels of command. These buildings in general are referred as “the Hammer Heads”. The Hammer Handles have three (3) floors with a crawl space at grade elevation. The Hammer Heads are single floor. The Basement area with a main utility mechanical & electrical room extends partially under both the Hammer Head and the Hammer Handle.

The definitive removal / demolition work items for each building will require:

a) Hazardous material / debris abatement and removal mostly within the crawl space

b) Partial at ~ 75% removal / demolition of exterior building envelope, interior walls, etc.

c) Removal at ~ 90% removal of building mechanical – electrical systems

d) Removal of the existing roof EPDM system (but not the roof framing structure)

The definitive repair / new work items for each building will require:

e) New exterior envelope

f) New building mechanical – electrical systems

g) New Thermoplastic Polyolefin (TPO) Roof system

h) Painting of exteriors

Other considerations for site work coordination:

i) New utility connections (mostly by other entities)

j) Shared construction boundaries with adjacent current and future projects
